The arrow travels a distance of 2145 meters into the bale of paper after 3 seconds.

The distance an arrow travels into a bale of paper is given by the equation \[ s(t)=2401-(7-t)^{4}, 0 \leq t \leq 7 \]. To find the distance the arrow travels at a specific time, we simply plug in the value of \( t \) into the equation and solve for \( s \).

For example, if we want to find the distance the arrow travels after 3 seconds, we would plug in \( t=3 \) into the equation:
\[ s(3)=2401-(7-3)^{4} \]
\[ s(3)=2401-(4)^{4} \]
\[ s(3)=2401-256 \]
\[ s(3)=2145 \]

Similarly, we can find the distance the arrow travels at any time \( t \) by plugging in the value of \( t \) into the equation and solving for \( s \). This will give us the distance the arrow travels horizontally into the bale of paper at that specific time.

The logistic function is then given by f(x) = 11 / (1 + e^(-0.75x))

The logistic function with the given properties is given by: f(x) = 11 / (1 + e^(-0.75x))

To understand this, we can start by noticing that for small values of x, f is approximately exponential and grows by 75% with every increase of 1 in x. This implies that the function can be written as f(x) = e^(0.75x). Since the limiting value of f is 11, the function can be written as f(x) = 11e^(0.75x). The logistic function is then given by f(x) = 11 / (1 + e^(-0.75x)), which satisfies the given conditions.

The equation of the line that is parallel to y = 2/5x + 2 and passes through (-5, 6) is y = (2/5)x + 8.

Perpendicular line slopes are the negative reciprocals of one another. In other words, any line that is perpendicular to a line with a slope of m will have a slope of -1/m. If lines are parallel if they have the same slope.

The slope of the given line is 2/5.

We know that, any line perpendicular to it will have a slope that is the negative reciprocal of 2/5, which is -5/2.

Using the point-slope form of a line:

y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Substituting the values we know:

y - 6 = (-5/2)(x - (-5))

y - 6 = (-5/2)x - (25/2)

y = (-5/2)x + 17.5

Therefore, the equation of the line perpendicular to y = 2/5x + 2 and passes through (-5, 6) is y = (-5/2)x + 17.5.

The slope of parallel lines are same. Thus, using point slope form:

y - 6 = (2/5)(x - (-5))

y - 6 = (2/5)x + 2

y = (2/5)x + 8

Therefore, the equation of the line that is parallel to y = 2/5x + 2 and passes through (-5, 6) is y = (2/5)x + 8.

Answer:

∠M = ∠P = 112

∠N = ∠Q = 68

Step-by-step explanation:

The interior angles of a quadrilateral always sum up to 360°.

since NP//MP and NM//PQ => ∠N = ∠Q and ∠M = ∠P

and ∠N + ∠Q + ∠M + ∠P = 360

∠M = ∠P

6x - 2 = 4x + 36

6x - 4x = 36 + 2

2x = 38

x = 38/2 = 19

=> ∠M = ∠P = 4(19) + 36 = 112

∠N + ∠Q + ∠M + ∠P = 360

2∠N + 2∠M = 360

∠N + ∠M = 180

∠N = 180 - ∠M = 180 - 112 = 68

∠N = ∠Q = 68

The ratio of their radii is 8/2 = 4.

Ratio is a comparison of two or more quantities expressed in terms of their relative sizes. It is a way to express one number as a fraction of another number. For example, if a person has three apples and two oranges, the ratio of apples to oranges can be expressed as 3:2. Ratios can also be expressed as fractions or percentages.

To show that Circle D and Circle E are similar, we need to determine if the ratio of their radii is equal to the ratio of their distances from the origin. The ratio of their radii is 8/2 = 4. The distance from the origin for Circle D is sqrt((8)²+ (-2)²) = sqrt(64 + 4) = sqrt(68) = 8.24. For Circle E, the distance from the origin is sqrt((5)² + (1)²) = sqrt(26) = 5.1. The ratio of their distances from the origin is 8.24/5.1 = 1.61. Since the ratio of their radii (4) is equal to the ratio of their distances from the origin (1.61), we can conclude that Circle D and Circle E are similar.

Use the identity \(\sec x=\frac{1}{\cos x}\) to simplify the expression:
\( (\csc x+\cot x)^{2}=\frac{\sec x+1}{\sec x-1} \)

To verify that the given equations are identities, we need to simplify the expressions on each side of the equation and show that they are equal. We can do this by using the trigonometric identities and algebraic manipulation.

a) \( \frac{\cos x}{\tan x+\sec x}=1-\sin x \)

Start by simplifying the left side of the equation:
\( \frac{\cos x}{\tan x+\sec x}=\frac{\cos x}{\frac{\sin x}{\cos x}+\frac{1}{\cos x}} \)

Multiply the numerator and denominator by \(\cos x\) to get rid of the fractions:
\( \frac{\cos x}{\tan x+\sec x}=\frac{\cos x \cdot \cos x}{\sin x+1} \)

Now, use the identity \(1-\sin^2 x=\cos^2 x\) to simplify the numerator:
\( \frac{\cos x}{\tan x+\sec x}=\frac{1-\sin^2 x}{\sin x+1} \)

Factor the numerator:
\( \frac{\cos x}{\tan x+\sec x}=\frac{(1-\sin x)(1+\sin x)}{\sin x+1} \)

Cancel out the common factor:
\( \frac{\cos x}{\tan x+\sec x}=1-\sin x \)

We have shown that the left side of the equation is equal to the right side, so the equation is an identity.

b) \( \frac{\sec x+1}{\sec x-1}=(\csc x+\cot x)^{2} \)

Start by simplifying the right side of the equation:
\( (\csc x+\cot x)^{2}=(\frac{1}{\sin x}+\frac{\cos x}{\sin x})^{2} \)

Expand the square:
\( (\csc x+\cot x)^{2}=\frac{1+2\cos x+\cos^2 x}{\sin^2 x} \)

Use the identity \(1-\cos^2 x=\sin^2 x\) to simplify the denominator:
\( (\csc x+\cot x)^{2}=\frac{1+2\cos x+\cos^2 x}{1-\cos^2 x} \)

Factor the denominator:
\( (\csc x+\cot x)^{2}=\frac{1+2\cos x+\cos^2 x}{(1-\cos x)(1+\cos x)} \)

Now, simplify the numerator by factoring:
\( (\csc x+\cot x)^{2}=\frac{(1+\cos x)^2}{(1-\cos x)(1+\cos x)} \)

Cancel out the common factor:
\( (\csc x+\cot x)^{2}=\frac{1+\cos x}{1-\cos x} \)

Finally, use the identity \(\sec x=\frac{1}{\cos x}\) to simplify the expression:
\( (\csc x+\cot x)^{2}=\frac{\sec x+1}{\sec x-1} \)

We have shown that the right side of the equation is equal to the left side, so the equation is an identity.

Answer: y = x + 8

Step-by-step explanation:

1 meter = 1000 millimeter

Answer: :)

Step-by-step explanation:

The metric system is based on the International System of Units (SI), which is a standardized system of measurement used worldwide. The SI unit for length is the meter, and all other units of length in the metric system are derived from it.

The relationship between millimeters and meters can be expressed mathematically as follows:

1 mm = 0.001 m

1 m = 1000 mm

This means that if you have a length measurement in millimeters, you can convert it to meters by dividing by 1000. Conversely, if you have a length measurement in meters, you can convert it to millimeters by multiplying by 1000.

For example, if you have a piece of wire that measures 500 mm long, you can convert this to meters as follows:

500 mm ÷ 1000 = 0.5 m

Similarly, if you have a piece of fabric that measures 2.5 m long, you can convert this to millimeters as follows:

2.5 m x 1000 = 2500 mm

In summary, the relationship between millimeters and meters is that they are both units of length in the metric system, with one meter being equal to 1000 millimeters.

The correct answer is option b. f -1(x) = |x| + 3; x ≥ -3.

To find the inverse of a function, we can switch the x and y values and solve for y. In this case, we can start with the original equation:
f(x) = |x| - 3
Switch the x and y values:
x = |y| - 3
Solve for y:
|x| = y + 3
|y| = x + 3

Since the original function has a domain of x ≥ 0, the inverse function will have a range of y ≥ 0. This means that the absolute value of y will always be positive, so we can drop the absolute value bars:
y = x + 3
So the inverse function is:
f -1(x) = x + 3

And since the original function has a domain of x ≥ 0, the inverse function will have a domain of x ≥ -3. So the final equation for the inverse function is: f -1(x) = x + 3; x ≥ -3

c. The probability that among the next ten applications, seven will be rejected is 0.48

d. The probability that among the next ten applications, between 1 and 8 applications is 0.95

The binomial distribution formula is used to calculate the probability of getting a certain number of successes (x) in a fixed number of independent trials (n) with a known probability of success (p) for each trial. The formula is:

Here we have

30% of the applications received for a position in a graduate school are rejected.

a) The number of rejected applications among the next 10 applications follows a binomial distribution with parameters n = 10 and p = 0.3.

The expected number of rejected applications is:

E(X) = np = 10 * 0.3 = 3

Hence, the expected number of applications rejected is 3

b) The probability of being rejected is 0.3

The probability that none of the next 15 applications will be rejected is:

P(X = 0) = (1 - p)ⁿ = (1 - 0.3)¹⁵= 0.042

Therefore, the probability that none of the next 15 applications will be rejected is 0.042 or approximately 4.2%.

c) The probability that 7 of the next ten applications will be rejected is:

By using the binomial distribution formula

P(X = 7) = (10, 7) × 0.3⁷ × 0.7³ =  

=  6435 × 0.0002187 × 0.343 = 0.48

Therefore, the probability that 7 of the next 10 applications will be rejected is 0.48 or approximately 48%.

d) The probability that between 1 and 8 (inclusive) of the next ten applications will be rejected is:

P(1 ≤ X ≤ 8) = P(X ≤ 8) - P(X ≤ 0) = Σ P(X = i) for i = 1 to 8

We can use the complement rule and calculate the probability of having 0 or 9 rejected applications, and subtract that from 1:

=> P(1 ≤ X ≤ 8) = 1 - [P(X = 0) + P(X = 9) + P(X = 10)]

= 1 - [(1 - p)ⁿ + (n, 1) × p¹ × (1 - p)⁽ⁿ⁻¹⁾ + (n, 0) × p⁰ × (1 - p)ⁿ]

= 1 - [(0.7)¹⁰ + ((10,1) × 0.3 × 0.7⁹) + (10, 0) (0.3)¹⁰]

= 1 - [ 0.02824 + 0.01210 + 0.000006]

= 1 - [ 0.040346]

= 0.95

Hence, The probability that between 1 and 8 (inclusive) of the next ten applications will be rejected is 0.95 or approximately 95%  

Therefore,

a. The expected number of applications rejected is 3  

b. The probability that among the next 15 applications, none will be rejected is 0.042

Step 2: Write down the constant term of the divisor polynomial with the opposite sign. In this case, the constant term is -4, so we write down 4.

Step 3: Bring down the first coefficient of the dividend polynomial, which is 2.

Step 4: Multiply the number brought down by the constant term of the divisor polynomial, and write the result under the next coefficient of the dividend polynomial. In this case, 2 * 4 = 8, so we write 8 under -10.

Step 5: Add the numbers in the column, and write the result below. In this case, -10 + 8 = -2.

Step 6: Repeat steps 4 and 5 until all the coefficients of the dividend polynomial have been used. In this case, we get:

In Claude's balance sheet, the liabilities are shown separately from the assets. The liabilities are the debts or obligations that Claude owes to others. To find the total value of Claude's liabilities, we need to add up all the amounts listed under liabilities.

However, before we do that, let's quickly review what assets are. Assets are things that have value and can be owned or controlled by a person or a company.

Next, we can eliminate the two larger options, $50,370 and $25,420, because they are higher than Claude's total assets, which are not given in the question. If the liabilities were greater than the assets, this would mean that Claude owes more than he owns, which would not be a good financial situation.

Information about possibility of occurrence is provided by probability. For instance, weather patterns are used by meteorologists to predict the possibility of rain. In order to understand the relationship between exposures and the risk of health outcomes, epidemiology uses probability theory.

a) Chance that six or more pages may have mistakes:

To get this probability, we can utilise the binomial probability formula:

P(X>=6) = 1-P(X<6)

where X is the number of pages with errors.

P(X<6) = P(X=0)+P(X=1)+P(X=2) +P(X=3)+P(X=4)+P(X=5)

For each term, using the binomial probability formula, we obtain:

P(X < 6) = 0.9124

Therefore, P(X >= 6) = 1 - P(X < 6) = 1 - 0.9124 = 0.0876

Hence, there is a 0.0876 percent chance that six or more pages will include errors.

b) Chance that there are errors on more than 10 pages:

Using the same method, we can discover:

P(X > 10) = P(X = 11) + P(X = 12) + ... + P(X = 200)

To find the likelihood, we can use a calculator or software because performing the math by hand can be very time-consuming. Using a calculator for the binomial distribution, we obtain:

P(X > 10) = 1.64 x 10⁻⁶ (rounded to 3 decimal places)

Hence, there is a roughly 10% chance that there will be errors on more than 10 pages. 1.64 x 10⁻⁶.

c) Probability that none of the pages contain errors:

P(X = 0) can be calculated using the binomial probability formula:

P(X = 0) = (200 choose 0) * (0.009)⁰ * (1 - 0.009)²⁰⁰

= 0.8196

As a result, 0.8196 percent of the pages are likely to be error-free.

d) Probability that fewer than five pages contain errors:

P(X<5)=P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)

Again, using the binomial probability formula for each term, we get:

P(X < 5) = 0.8151

Hence, the likelihood that fewer than five pages are mistake-free is 0.8151.
